REGULAR CARE

TEMPERATURE PRESSURE RELIEF VALVE
This valve is near the top of the water heater and is essential for its safe operation. It is possible for the valve
to release a little water through the drain line during each heating period. This occurs as the water is heated
and expands by approximately 1/50 of its volume.
Continuous leakage of water from the valve and its drain line may
"Temperature
indicate a problem with the water heater (refer to
Pressure Relief Valve Running"
on page 14).
Warning: Never block the outlet of this valve or its drain line for
any reason.
Operate the easing lever on the temperature pressure relief valve
once every six months. It is very important you raise and lower
the lever gently.
DANGER: Failure to do this may result in the water heater
cylinder failing, or under certain circumstances, exploding.
If water does not flow freely from the drain line when the lever is
lifted, then the water heater should be checked by your nearest
Rheem Service Department or Accredited Service Agent.
The temperature pressure relief valve should be checked for
performance or replaced at intervals not exceeding 5 years, or more
frequently in areas where there is a high incidence of water deposits

HEAT PUMP SYSTEM
It is recommended the evaporator and refrigeration system is checked every five years. In particularly dusty
environments, it may be necessary to have the heat pump system checked and cleaned of dust and residue
on a more regular basis.
